Mathematics
1 answer:
pashok25 [27]3 years ago

Answer:

Step-by-step explanation:

9.1 h + 11.6 t = 9.98(60)

9.1 h + 11.6 t = 598.8 ........ <em>(1)</em>

h + t = 60 ........ <em>(2)</em>

h = 60 - t

9.1(60 - t) + 11.6 t = 598.8

546 - 9.1 t + 11.6 t = 598.8

2.5 t = 52.8

<em>t</em> = 52.8 ÷ 2.5 = <em>21.12</em><em> </em><em>≈</em><em> 21</em> (lb.)

<em>h</em> = 60 - 21.12 = <em>38.88 ≈</em><em> 39</em> (lb.)

A company has a cost equation of c=0.925x^2-4x+20 and a profit equation of p=-1.125x^2+6x+40. Solve for the breakeven point.
lana66690 [7]
0.925x^2 - 4x + 20 = -1.125x^2 + 6x + 40 (at break even point)

2.05x^2 - 10x - 20 = 0

x =  [ - (-10) +/- sqrt(100 - 4*2.05*-20) / (2*2.05) 

x =  6.40, -1.52   Ignore the negative 

Answer is  6.40
